Apera Model LabSen 751 – Titanium Body Food pH Probe

Apera Instruments LabSen® 751 Titanium-Body Non-Refillable Spear pH Electrode for Food Samples

Brand: APERA Instruments
Model: LabSen® 751
SKU: AI3157
Product Type: Non-Refillable Spear pH Electrode

Product Description

The Apera Instruments LabSen® 751 Titanium-Body Non-Refillable Spear pH Electrode is a specialized pH electrode designed for direct measurement of various solid, semi-solid, and suitable food samples. This electrode uses a spear-shaped sensor design that allows the measuring tip to be placed directly into samples such as cheese, fruit, dough, sushi rice, and meat products.

The LabSen 751 uses a LabSen S-Type Glass Membrane designed to provide fast response and high mechanical strength. This design helps the electrode produce fast measurement response while supporting use in food testing applications.

One of the main advantages of the LabSen 751 is its use of a food-grade titanium housing. Titanium material is used as the electrode body to provide a strong construction suitable for measurement applications on food samples that require materials appropriate for such use.

This electrode uses an Open & Ceramic Double-Junction system with polymer electrolyte. This combination is designed to support reference system stability and reduce the influence of the sample on the reference system during the measurement process.

The LabSen 751 is also equipped with a Long-Life Reference System, designed to improve reference stability and help extend the electrode’s service life. Because it uses a non-refillable design, the electrode does not require refilling of the reference solution during normal use.

With a measurement range of 0–14 pH, a temperature range of 0–80°C, a 1-meter cable, and a BNC connector, the LabSen 751 can be used with compatible pH meters. This electrode is highly suitable for food laboratories, the food industry, research, and quality control activities.

LabSen S-Type Glass Membrane

The LabSen 751 uses an S-Type Glass Membrane designed to produce fast response while having good mechanical resistance. This characteristic is important in food testing applications because the sensor must be able to respond quickly to pH changes when measuring various samples.

The spear-like membrane and electrode tip shape allow the sensor to be used directly on suitable samples without always having to prepare a solution or slurry first.

Food-Grade Titanium Housing

The body of the LabSen 751 uses food-grade titanium, which provides a strong construction suitable for food sample measurement applications. The body material also helps protect the internal components of the electrode during routine use.

This titanium design is combined with a spear tip measuring Ø6 × 50 mm, so the electrode can be used for direct penetration into suitable food samples.

Long-Life Reference System

The LabSen 751 uses a Long-Life Reference System designed to improve reference system stability and extend the electrode’s service life.

The Open & Ceramic Double-Junction system with polymer electrolyte helps maintain reference stability during measurement. Because the electrode uses a non-refillable design, users do not need to refill the reference electrolyte solution during normal use.

To maintain electrode performance, storage must be done using a 3M KCl soaking solution as recommended by the manufacturer.

Applications

The Apera Instruments LabSen 751 can be used for various pH measurement needs, especially in the food and food product sector, such as:

• pH testing of cheese.

• pH testing of fruit.

• pH testing of dough.

• pH testing of sushi rice.

• pH testing of meat products.

• Testing of solid and semi-solid food ingredients.

• Food analysis laboratories.

• Food processing industry.

• Food product research and development.

• Food product quality control.

• Testing of raw materials and products during production processes.

Advantages of the LabSen 751 for Food Testing

The LabSen 751 combines several characteristics that are important for food testing: spear sensor, S-Type Glass Membrane, food-grade titanium housing, and Long-Life Reference System.

The spear design allows direct measurement on suitable samples, while the S-Type Glass Membrane helps provide fast response. The titanium body provides a strong construction, while the long-life reference system helps maintain electrode stability.

This combination makes the LabSen 751 suitable for laboratories and industries that perform routine food pH testing and require an electrode specifically designed for solid or semi-solid samples.
